چکیده

دراین مقاله تاثیر میدان مغناطیسی حاصل از برهمکنش لیزر پرشدت فمتوثانیه ای با پلاسمای کم چگال در رژیم حبابی روی شتاب بسته الکترونی با توزیع یکنواخت گاوسی در سرعت و مکان مورد بررسی قرار گرفته است. دیده شد که میدان مغناطیسی می تواند انرژی نهایی بسته الکترونی را از حدود 1GeVبه حدود 1.2GeVافزایش دهد و پهن شدگی انرژی نهایی را کاهش دهد. همچنین واگرایی نهایی بسته الکترونی نیز در حدود یک مرتبه بزرگی کاهش یافته و برابر با 3-^10*0.38 میلی متر میلی رادیان شده است. علاوه براین، ما مشاهده کردیم میدان مغناطیسی باعث افزایش ده درصدی تعداد الکترونهای شتاب گرفته می شود.

The effect of magnetic field generated by the interaction of high-intensity laser pulse and low-density plasma on electron bunch acceleration in the bubble regime

چکیده [English]

In this paper, the effect of the magnetic field generated by the interaction of femtosecond high-intensity laser with under-dense plasma in the bubble regime on the acceleration of an electron bunch with Gaussian distribution in velocity and position has been studied. It was seen that the magnetic field could increase the final energy of electron bunch from about 1 GeV to approximately 1.2 GeV and reduces the final energy spread. Also, the final emittance of electron bunch decreased about one order of magnitude and it has been equal to 0.38 * 10^-3 mm mrad. Moreover, we observed that the magnetic field caused ten percent increment in number of accelerated electrons.
